The use of actigraphy in clinical practice for the assessment of sleep disorders in Parkinson’s disease dementia

摘要

BackgroundDementia in Parkinson’s disease dementia (PDD) and Lewy Body Dementia (LBD) are commonly associated with sleep disturbances, including rapid eye movement (REM) sleep behaviour disorder, which have a significant negative impact on quality of life. Sleep monitoring using polysomnography is poorly tolerated in patients with dementia. An alternative is the use of actigraphy. Sleep wake patterns are estimated from periods of activity and inactivity and provides statistics of sleep quality. Actigraphy has previously been used in Parkinson’s disease to quantify bradykinesia and assess sleep disorders but not specifically in those with dementia.
